[IFC Tunnel] [Geotechnics] Map "spatial" containers

MappedZone (FieldOutcrop, TunnelFace, TunnelWallArea, SlopeArea), TestedZone
Input for TunnelWallArea:

Description from RAR: “All the registrations in the system are localized geometrically along the tunnel. The tunnel cross-section is developed (unfolded) so that the width of the registration plan corresponds to the arc length of the theoretical perimeter.”
This way of describing and breaking down the tunnel “shell” is a typical way both for mapping geotechnical and geological observations and a way for describing where to apply certain types of built elements such as rock support measures, painting etc.
Notes from meeting (@larswik , @SergejMuhic & Jan Erik Hoel) 2022-02-14):
This does not seem to be a very exact science. Typically the “green lines” occur where the tunnel perimeter intersects a +/-45 degree plane (measured from the “tilted” floor). However, it seems important from both the geotechnics and construction side that these kinds of descriptions, where information is stored for each “cell” (above right) can be exchanged with IFC.
